Android Lint简介（转）

If you have the SDK tools/ directory on your path, you can invoke it as “lint”. Just point to a specific Android project directory. You can also point to a random directory, which (if it is not an Android project) will be searched recursively and all projects under that directory will be checked. (And you can also specify multiple projects separated by spaces)

$ lint --disable MissingTranslation,UnusedIds,Usability:Icons /src/astrid/

$ lint --disable MissingTranslation,UnusedIds,Usability:Icons /src/astrid/

Valid issue id's:
"ContentDescription": Ensures that image widgets provide a contentDescription
"DuplicateIds": Checks for duplicate ids within a single layout
"StateListReachable": Looks for unreachable states in a <selector>
"InefficientWeight": Looks for inefficient weight declarations in LinearLayouts
"ScrollViewSize": Checks that ScrollViews use wrap_content in scrolling dimension
"MergeRootFrame": Checks whether a root <FrameLayout> can be replaced with a <merge> tag
...

Priority: 8 / 10
Severity: Warning
Category: Correctness

Most Android views have attributes in the Android namespace. When
referencing these attributes you *must* include the namespace prefix,
or your attribute will be interpreted by aapt as just a custom
attribute.

• Automatic fixes for many warnings自动修正大量警告
• Lint gets run automatically on various editing operations当编辑操作完成后，立即自动运行
• Ability to suppress types of errors as well as specific instances of an error可以suppress(忽略)一种类型的erro，也可以suppress(忽略)特定的一个erro
• Ability to configure issue severities能够配置issue（问题）的severities(严重性)
• Jump directly to the problem source from the lint view通过lint视图能直接跳转到其问题对应的源码处

• Export an APK. In this case it runs lint in a special mode which only looks for fatal errors (which is faster) and aborts the export if any fatal errors are found. You can turn off this in the Lint Options.在导出APK文件的时候，lint会做快速的扫描，以寻找fatal的错误。如果发现有fatal的错误，导出APK的操作将被迫终止
• Edit and Save and XML file, such as a layout file or a manifest file. In this case, all the file-scope checks that apply to the given file are run and editor markers are added for any issues found.编辑和保存XML文件，lint也会自动扫描这些文件。另外从ADT20开始，对于java源码文件在编辑和保存后，lint也会对他们进行扫描。
• Use the layout editor. After every UI operation, file-scope checks (such as the various layoutopt rules) are run on the layout file and the results are shown in a special lint window (which can be opened from the error marker which shows in the top right corner of the layout editor when errors are found).对于使用layout editor来操作布局文件时，在每个UI操作后,lint也会自动扫描该布局文件。

•  Refresh, which re-runs the current analysis on the same projects
•  Fix, which automatically fixes the issue (this applies to issues where a quickfix is available)
•  Suppress this issue with an attribute or annotation
•  Ignore in this file (saves suppress information in lint.xml)
•  Ignore in this project (ditto)
•  Always ignore
•  Delete this lint marker
•  Delete all lint markers
•  Expand All, 
   Collapse All
•   Configure Columns用于设置在lint Window中对于检查出的issue的哪些项显示哪些项不显示，如图3-7所示
   
•  Edit Options Edit Options 点击该按钮会弹出Lint Preference dialog，如图1或图3-8在里面你可以定制默认/全局的Android Lint的基本检查规则，在其中可以设置所有项目默认的lint检查规则的检查级别，把检查级别(Severity)设为”ignore“,其实就是忽略（suppress）该检查规则

The Edit Options actions brings up the Lint Preference dialog, which has also been improved.  You can now search through the options by filter:

 3.3、Quick Fixes

• From the lint view（如图3-6所示）, click the lightbulb 
   to invoke a fix.
• From the layout editor warning summary, click the Fix button to fix.
• And from the XML source editor, invoke the Quick Fix (Ctrl-1 or Command-1) and pick the quick fix associated with the warning.

• Ignore the warning in this file only
• Ignore the warning in this project
• Ignore the warning, period.
• Ignore warnings using annotations or attributes, as explained here.

These choices are stored in a file named lint.xml in the project, which is also read by the command line tool. Thus, you can ignore warnings from the UI, and check in thelint.xml file with your source projects, and others running lint will not see warnings you have ignored (presumably because they have been manually verified).
